GEORGE G. TANNER, OF INDIANAPOLIS, INDIANA.

GRAIN-CAR DOOR.

SPECIFICATION forming part of Letters Application tiled August 9, 1881.

To all whom it may concern:

Be it known that l. GEORGE G. TANNER, a` citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Improvement in Grain -Car Doors, of which the following is a specification.

My invention relates to improvements in grain-car doors and nfode of operating them; and the objects of my invention are, rst, to provide the grain -car door with means for holding it suspended when elevated to the top of the car; second, to afford facilities in the slide-rail of the door for permitting the wide and narrow hooks at each end of the door to pass above the slide-rail; and, third, to provide a means for holding the-door in position after being elevated and slid toward one end of the car. These objects I accomplish by the devices illustrated in the accompanying draw ings, in which- Figure 1 represents a view of the inside of a car, showing the arrangements ot' parts fully. Fig. 2 is a cross-section taken at the line tr a', Fig. l. Fig. 3 is a cross-section taken at the line y y, Fig. l. Fig. et is an enlarged crosssection of the door elevated and the upper portion of the car at the line a' Fig. l. Fig. 5 is a cross-section of the same, with the door elevated, taken at theline z z, Fig. 1. Fig. 6 is an enlarged front view of the stop mechanism for holding the door in position when elevated and slid to one end ofthe car, and Fig. 7 is a top view of Fig. 6.

Similar letters refer to like parts throughout the several views.

A represents the side of the car; B, the doorway; G, the grain-car door, and D D the vertical strips between which and the side of the car the door slides vertically.

G and G represent the two sections of the sliderail, which are secured to the top of the side of the car, projecting sufciently far in ward to permit the hooks E E of the door to operate thereon. The hook E of the door is narrow, and passes through the narrow opening J, between the two sections G and G' of the slide-rail. E represents the other hook of the car-door, which, when elevated with the door, passes-through the space F above the rail G.

Patent No. 261,883, dated August 1, 1882.

(No model.)

P represents a plate fastened to the central portion of thetop of the car-door, below which,

on the outside of the door, is agroove,b. The

downwardly-hanging hook R is hinged at its upper endto the upper side piece, A', and the hook H, at the bottom, operatesin the groove b below the plate P. This hook is held forward by the push-spring c at the back. The hook is also provided with a lever-arn1,1,pro jecting inward, by means ot' which the hook is operated to release the door, as shown more fully in Fig. 4.

The hooks E and E of the door C, (when the door G is elevated to the top of the opening B) pass through the openings J and F of the rail G G. At the same time the plate P moves the hook H back untilv it is above the hook, when the spring a reacts and forces the hook into the groove b. The groove b is long enough to support the door on the hook H until the hooks E' and E are moved over onto the side rails ,G G,the hook E sliding on the rail G and the hook E sliding on the rail G. The hook "E, being wider than the hook E', passes over the opening J without any interruption. the car, as indicated by dotted lines in Fig.1, the hook E' passes under the point d of the pawl K, said pawl being forced down behind the hook E by the spring L. The pawl K is lifted by the lug M when it is desired to move the door forward over the opening B, all of which is shown more fully in Figs. 6 and 7. When the door C has been slid forward -over the opening B the hook H enters the groove b and prevents the door from dropping until released by a downward pressure on the lever-arm Iof the hook R, which,when the hook H is released from the plate P, permits the door to be lowered into its position, as shown in Fig. 1.

What I claim as new, and desire to secure by Letters Patent, is- 4 1. The grain-car door C, provided at one end with the narrow hook E and at the other end with awide hook, E, and the central upper edge provided with a metallic plate, P, with a groove, b, below it, combined with the slide-railG G', having narrow opening J for the hook E and wide opening F for the hook E to pass through, the hinged hook R, with When the door is slid to one end of v IOO lever-arm I, hook H, and spring a, substanthe hook E to pass through, substantially as tially as shown and described. shown and described.
